Study "Theoretical Physics" if you are inclined to. Everybody will be happy if you acknowledge:
1. It isn't relevant to most of the jobs.
2. You aren't entitled to a job.
3. etc...
This condescending arrogance is a simple example of the Dunning-Kruger effect. Most academic disciplines have little application in the workplace. Education has a deeper purpose than you think. The mechanism by which educated people get ahead in society is far more complex and subtle than the "learn useful work skills => better at work => more promotions" caricature.
